Article II Landscape, Screening, and Fencing
Section 425.070 Tree Protection
a. No more than 70 percent of the total tree canopy coverage on any
development site may be removed or destroyed, except as follows:
(1) Up to 100 percent of the total tree canopy coverage on any development
site may be removed or destroyed when the owner can provide evidence
of extreme topography, uniqueness, unusual lot shape or similar
circumstances which results in an inability to provide tree preservation.
(2) In such cases, new trees shall be planted in addition to other trees
required by this Article, so that the combined remaining and proposed tree
canopy coverage on the development site equals 30 percent or more. For
the purposes of these calculations, the tree canopy coverage potential as
specified in Table 425.070.C.2 shall be used for proposed trees:
Table 425.070.C.2, Tree Canopy Coverage Potential
Tree Group Tree canopy coverage
potential
Deciduous-Large 750 square feet
Deciduous-Medium 500 square feet
Deciduous- 250 square feet

(3) A mitigation planting plan shall be submitted that shows the location, size,
species, and tree canopy coverage potential of trees that are to be planted
on-site.
(4) If spatial limitations prohibit the ability to replant all required trees on the
site, the City may accept a plan to plant the additional trees on a City-
owned site or the City may accept a payment into an established tree
bank for use by the City to plant or maintain public trees in the future. The
payment will equal the reasonable cost to plant the required trees.
b. Trees within 100 feet of natural watercourses or water bodies shall be
protected. An exception will be granted if the only access to the site is through
the natural watercourses or water body. These trees will take precedence
over all other trees on the tract for protection.
3. Tree Protection Measures

protected under this Article, the Certified Tree Arborist having prepared the
Tree Stand Delineation Study (TSD) and the Tree Preservation Plan (TPP) for
the subject property shall:
(1) Mark on the property, with construction fencing or other appropriate
barricade, the limits of disturbance beyond which no grading will occur as
such limits are identified on the approved TPP; and

approved TPP.

responsible for the maintenance of required protection measures throughout
the construction of the project until a certificate of occupancy or other final
permit is issued.
4. Tree Replacement
a. Financial Guarantee
(1) The developer shall post a financial guarantee for the benefit of the City to
account for trees that die, or are damaged beyond repair, as a result of
grading or construction damage within a two year period after the
issuance of final occupancy permits.
(2) The required financial guarantee may be in the form of cash, letter of
credit or surety bond.
(3) The amount of the required financial guarantee shall be in the amount of
$2,000 for each acre of the tree preservation area or $10,000, whichever
is greater.
b. Prior to Occupancy
(1) Prior to issuing any occupancy permits, should any preserved tree die or
become damaged as a result of grading or construction, the developer will
pay a non-refundable assessment equal to the value of the trees that die,
are damaged or are removed.
(2) The value of the trees will be determined using the International Society of
Arboriculture's methodology of tree appraisal.
(3) The City will withhold any occupancy permits until the assessment is paid.
c. Post Occupancy
(1) Within a two-year period after the occupancy permit is issued, the
developer shall replace protected trees that die or are damaged beyond
repair, as a result of grading or construction damage, as determined by a
certified arborist.
(2) The number of replacement trees is determined by matching the
combined caliper of trees to be planted with the diameter (DBH) of trees
that were lost.
(3) Failure to plant the required replacement trees shall constitute default and
the City shall be entitled to proceed against the financial guarantee.
(4) If spatial limitations prohibit the ability to replant all required trees on the
site, the City may accept a plan to plant the additional trees on a City-
owned site or the City may accept a payment into an established tree
bank for use by the City to plant or maintain public trees in the future. The
payment will equal the reasonable cost to plant the required trees.
